Why Choose the Finder 62.22.8.048.4300 Industrial Power Relay?
The Finder 62.22.8.048.4300 is a high-performance 16 A industrial PCB-mounted power relay designed for reliable electrical switching in industrial automation, machinery and power control applications. Featuring a 48 V AC operating coil and two normally open (2 NO) contacts, this relay provides dependable switching of two electrical circuits from a single control signal. As part of the established Finder 62 Series power relay range, it combines robust construction, high switching capacity and reinforced electrical insulation.
The 62.22-4300 configuration is specifically designed with a double-pole single-throw normally open (DPST-NO) contact arrangement and a contact gap of at least 3 mm. Unlike the standard 62.22 changeover version, this model uses two normally open contacts intended for applications requiring greater contact separation. Its silver tin oxide (AgSnO2) contacts provide robust switching performance, particularly where electrical loads generate significant inrush currents.
With a 16 A rated contact current, 48 V AC coil supply and 4000 VA rated AC-1 switching capacity, the Finder 62.22.8.048.4300 is suitable for industrial heating equipment, lighting control, electrical power management and automated machinery. Its PCB mounting design allows direct integration into electronic control assemblies, making it a practical choice for OEM manufacturers and industrial equipment designers.

High-Current Switching with Enhanced Contact Separation
The Finder 62.22.8.048.4300 uses an electromagnetic switching mechanism to control two normally open electrical circuits. When the 48 V AC coil is energised, both normally open contacts close, allowing current to flow through their respective circuits. When the coil supply is removed, the contacts return to their open positions. The DPST-NO arrangement is particularly useful where two circuits must be energised together without requiring changeover contacts.
The Finder 62 Series is designed for industrial applications requiring high switching currents, reliable insulation and durable electrical contacts. The 62.22-4300 variant provides a contact gap of at least 3 mm, making it suitable for equipment designs that require enhanced open-contact separation. Its silver tin oxide contacts and high short-duration peak current capability make it a practical choice for switching resistive loads and equipment with demanding inrush characteristics, provided the relevant manufacturer load ratings are observed.
